@"DavecUK"#p12737 Thanks Dave.. interesting because it occurrs to me the Vesuvius plus a bluetooth connection and the right programming would be the perfect synthesis of build quality (ECM) innovation (Decent) all wrapped in a traditional E61 style body. Can you convince @"Paolo_Cortese"#90 to update it? I love mine, which I bought second hand largely on the basis of your reviews; its taken me a year but I think I've finally got the hang of it!

@"Grahamsphillips"#p13074 I'd put an order in for one of those!

> @"Grahamsphillips"#p13074 Can you convince [@Paolo_Cortese](https://coffeetime.freeflarum.com/u/Paolo_Cortese) to update it? It would mean losing that lovely old, but proven super reliable main board…..

hi, could some one with a vesuvius with the wood/metal handle please email off my sig

I have a wooden handled bottomless pf (generic) that I bought for my Elizabeth then a barista pro IMS basket in it. Will this IMS basket fit the supplied bottomless pf that comes with the Vesuvius?

So, my Vesuvius arrived today. I didn’t want to start another thread and this looked like the most appropriate place to discuss my first day! It left Italy last Friday and arrived in my house today - 6 days, yipee! Mine was definitely used, the plastic was gone from it, there was dirt here and there, spilled water underneath the water tank and for some reason the pipes going onto the tank had a black residue of some sort on parts of them. The panel on top of the machine, where the cup test sits is pretty badly finished with dirty plastic covering it but doesn’t bother me. I didn’t pay for a brand new machine I guess!! Assembling was easy as the provided guide is comprehensive (remember the first thing you do is unscrew the four screws on the top of the side panels, no hammer or anything required) The Teflon furniture gliders I pre purchased are perfect for moving it around on the counter top. A bag of felt pads come with the machine. I put 1L through the group 200ml at a time with at least 15 seconds in between. I then emptied the service boiler twice as per manual. I noticed the shower screen had coffee on it so I soaked that in puly caff and gave a good wash. At this stage I only had time to pull 4 shots as I had to leave! I was close to dialled in by the fourth albeit a bit long but I took it with me in the car- I have to say it was very very nice. So I look forward to playing with it tomorrow. I thought I had a dodgy touch screen as it didn’t seem to respond some times but apparently there are different delay times for different choices on it.. phew..! Looks a stunning machine on the counter and I love the almost totally silent pump. I thought the water reservoir wasn’t the best design but I think I’ll get used to it and won’t have to be refilling it so often when I’m not flushing the system through and just using it to make coffee! It really is a different operation to the Elizabeth but I don’t think it will take long to get used to it. So, I can’t wait to drink coffee from it tomorrow

[upl-image-preview url=//i.imgur.com/cumOEwk.jpeg] I use this type of oil can to fill any of my machines with water.

@"DavecUK"#p13617 I ordered this one by someone’s recommendation on here: https://www.toolstation.com/laser-plastic-measuring-jug/p20428 Seems really ok although the spout is not very flexible

@"prezes"#p13619 mines very similar and probably on something from nu-man, the image I found seems to have brewers droop.

I used a plastic 2 litre water bottle today!

Vesuvius Pressure Profiling Machine - General Discussion

Gagaryn

AJuar SAME PID AND PUMP CONFIGURATION

Bizarre. The pump is clearly accelerating much quicker with the steam boiler on. I have no idea why that would be I’m afraid but I’m sure somebody will.

DavecUK

AJuar Then, I must say that I take care of Dave’s holidays inconvenience, because it is difficult to “cause the machine to fail”, however in my personal morning routine it’s very easy. I will explain this: the machine switches on automatically at 6:50 a.m., I wake up at 7:20 a.m. and I make coffee at 7:30 a.m. When I arrive in front of the machine, the steam boiler is normally at eco mode (12 minutes for eco mode because the machine reaches the temperature in less than 10 minutes), then I make coffee, while the steam boiler rises to 130 degrees Celsius. If I wait a little more time, or if I touch the screen, the steam boiler warm up, and if it rises 130º (approximately) IN THIS CASE THE MACHINE FAIL

Try this test run the machine and steam boiler in a way that there would be a failure e.g. reaches 130C. But just before you pull the shot, switch the steam boiler off…..what happens?

The idea of this is to eliminate temperature of the steam boiler to be the cause….or the fact that’s it an electrical issue due to the the steam boiler being heated.
The other test is to change the boiler priority, then enter a potential fail condition with a reversed boiler priority

The above would be 2 separate tests!

tocateclas

DavecUK Thank you, I’ll try both.

AJuar

DavecUK Like yesterday, in the afternoon the Vesuvius didn’t fail at all. This is another information that could be important? It only fails in the morning, when the machine is cold, after all night switched off, and it warms from less temperature. Perhaps a valve? I really don’t know, I have no idea.

Thank you very much, tomorrow morning I will do the two suggested tests.

AJuar

DavecUK I have made the two tests, and in both cases the machine tends to fail in a potential failure condition (not always). Also, in one case out of 20 approximately, with the boiler priority, the machine has showed very different pressure behaviour even with the steam boiler off, from cold. I have the video of this but I’m not going to upload because I know that you trust me. This should be an evidence of a capricious mechanical little valve stuck? I don’t know.

To sum up, the machine:

- WITH THE SAME PID CONFIGURATION THE MACHINE MAKES DIFFERENT EXTRACTIONS.

- The machine shows an astonishing regular behaviour with the STEAM BOILER OFF. She makes GREAT COFFEE, or very predictable or regular extractions.

- There is some relationship between the pressure of the STEAM BOILER, because the machine fails an high percentage of times with the STEAM BOILER ON, or with high temperature in any part of the internal machine.

I know that this failure is difficult to solve, but I hope that ACS technicians have the time and the capacity to investigate with the @kautivo Vesuvius machine to try to identify the CAUSE of this capricious failure in order to solve it. If not, I assume that ACS Vesuvius works like this and I’ll continue to make the coffee with my little annoying morning routine (switching off and on the steam boiler in the morning).

Thanks!

tocateclas

AJuar My solution for this is switching off the steam boiler before coffee extraction, making the coffee, and then, switching on the steam boiler (with tactile screen it’s very easy and the boiler reaches the temperature quickly) and then I steam the milk. Also, If I make the coffee quickly with eco mode, not problem. I was happy with this, it was not a problem for me, and the Vesuvius coffee is really great, I had assumed this little inconvenience. If I insist with this is only out of pure curiosity, and also to collaborate with my friend @kautivo. When he said to me that Dave and Paolo would look at his machine, I was happy because I thought that you really would find the CAUSE of the problem (it is more important for me than the solution or any partial solution like adapting the pid configuration). Well, in fact it’s not really important for me, I have also spent time with this and I was also determined not to spend more time and effort. I had adapted my morning routine.

Yes, that is what I’m doing for years. Not switching the boiler off but playing with the eco mode to keep temperature under 120º. I have adapted my routine, yes, it works ok this way but… it’s annoying.

Tap required to clean out these threads. what size?

DavecUK

finally today i have time to look at the V

as you said, pain in the A to get access but my steam valve is behind the electrics no the boilers so 1% easier!!!

As suspected no thread locker on the valve on the rear side. BUT it did have from the factory, Previous owner “hasn’t worked on it” Well, someone clearly has! threads totally dry and easily removed by hand.

Dave do you know the correct tap size please to clean out the old thread locker on the back side of the valve.

Also what semi permanent thread locker would you use to re-assemble?

DavecUK

Adrianmsmith Dave do you know the correct tap size please to clean out the old thread locker on the back side of the valve.

Also what semi permanent thread locker would you use to re-assemble?

I would simply use a very small jewellers type screwdriver to un down the thread, you don’t need a tap and only need to get the loose stuff out.

Loxeal 18:10 is a good semipermanent thread locker, you will only need one or two drops…personally though I would try PTFE tape first as it’s much much cheaper and should work fine.

I took this wand apart completely and assembled it with Loxeal 18:10 https://www.ebay.co.uk/itm/314135700947?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338723872&toolid=20006&customid=ll0fvV4aAAAAiyt0J_JRzj-leU4wAAAAAA

You can also use Loctite 542

Vesuvius leak free for a week now 🫣
Second repair attempt.
First attempt I assembled as it should be
My issue has been getting the outside and inside elbow “tight” in the correct orientation.
Tried it anyway using ptfe thread locker .
Worked ok for 3 days and started weaping again.
Guess as the thread locker went hard the steam found it’s way around.this was not the stuff Dave recommended I have to say. Just a Screwfix special.

I’ve had a bee in my bonnet for a while about the choice of fittings used so have changed the elbow on the back of the steam valve to a ¼ to 8mm compression straight fitting. Can now get everything nice and tight and not have to worry about orientation. This time I got a new ptfe washer from acs (when I got the evo oak handles last month) could not get correct thickness on Amazon. Just used ptfe tape on the screw fittings font and on my new coupling.
Am in to the second week now and leak free!!

Forgot to photo the pipework prior to assembly!!

Will do the same to the other valve if I ever need to disturb it .

Spid3r00

AJuar Sorry to not following the history of entire discussion… anyway my question if this behavior is happening regardless if steam boiler in in ECO-mode or not?

DavecUK

AJuar DavecUK I have made the two tests, and in both cases the machine tends to fail in a potential failure condition (not always). Also, in one case out of 20 approximately, with the boiler priority, the machine has showed very different pressure behaviour even with the steam boiler off, from cold. I have the video of this but I’m not going to upload because I know that you trust me. This should be an evidence of a capricious mechanical little valve stuck? I don’t know.

You have ruled out software as the issue then because if it was a software bug it would fail every time.

I cannot understand how a valve or plumbing would have this effect. You tried with HX off and on which includes or eliminates the 2 halves of the brew circuit, and noticed the same behaviour. This means those sections of the brew circuit cannot be at fault?

Logically this leads to the fault being outside the sealed brew circuit (or at either end of it)…but it doesn’t make sense on how this could have the effects you are observing?

If it’s the pump end, there is always "push from the pump and I can’t see how an intermittently leaky 1 way valve would have this effect
A leaky autofill valve would drop the pressure but you would see the service boiler overfilling over time (you should check this). Even so, I don’t see how a leak could cause a pressure peak, unless it’s chattering (leaking on/off/on/off), possibly that might affect the PIDs ability to control the pump. Even so if it was leaking why only when the steam boiler is on…perhaps it’s warming up and then the defect is showing? It might be the reason why the fault doesn’t present itself until the service boiler has been on a while?

So check whether the boiler is overfilling and if it is it might be the autofill valve…?

My confusion about the autofill valve is 4 machines, all done it from new, all with faulty autofill valves that cause PID issues in a particular way when the service boiler is on…..doesn’t sound very probable does it. Especially as I am only guessing on something having this effect.

If I’m honest I don’t know, it doesn’t make sense and I couldn’t reproduce it, which means I couldn’t find the cause?

kautivo

Spid3r00 my friend in Eco mode the steam boiler is with low temperature then there isn’t fail…

Cuprajake

what dose it do at different stem boiler temps? 120 -125 -130 etc,

kautivo

Cuprajake the dosis is the same, 17g or 18g the fail happens when the steam boiler is over 120°…

Cuprajake

but under 120 fine?

kautivo

Cuprajake yes but there are a big difference when you froth the milk…it’s better over 125° we have checked i hope they find where is the problem.

Cuprajake

i personally have all my machines at 125,

have you tried 123 and a two hole tip,

its a very weird fault

kautivo

Cuprajake but the machine must work right independient of the temperature steam boiler…have you check your machine with 128° ?

Cuprajake

i have a bianca

kautivo

Cuprajake ok, good machine!

kautivo

DavecUK i have to give thanks again your effort to try help us and to resolve the problem in our Vesuvius! I hope before or after we know where is the problem.

Thanks a lot!

AJuar

DavecUK Thanks! It sounds viable. This morning I have purged the water of the steam wand and the first time 17-18 g of water come out before the steam. Is this normal? Is there another way to check the service boiler level? Where is the autofill valve placed? Could I buy another valve and replace it or it’s an electrical problem? Please, send me the diagram of the Vesuvius or the code of the autofill valve, in order to buy another if it is necessary. Also, the chattering that you mention is an electrical issue, then I’m really not capable of checking electrical issues.

Please let me know. Is it possible to check these things in the factory with the @kautivo coffee machine?

Thank you very much
